The lac operon is just one specific example of an operon that is regulated both negatively, by binding of a repressor, and positively by catabolite repression.  Describe another example of this type, providing details of the ligands that positively and negatively regulate transcription of the operon, and briefly describe the genes in the operon and the molecular logic of the specific operon you describe.

The lac operon is regulated via positive and negative regulation. Explain how each mechanism works on this operon, and under which circumstances will the operon be turned on. Include the definition of an operon 2. What are the advantages to a microbe of having inducible enzymes? What is the function of toluene in the experiment where you induced enzyme function?

1) 4pts - The presence of glucose in the environment prevents lots of lac operon expression, while glucose’s absence greatly increases expression – discuss how ATP concentration, adenylyl cyclase, and CAP/cAMP and holoenzyme increase lac operon expression. 2) Discuss how promoters, enhancers and the TF proteins that interact with them are used in eukaryotic cells to control transcription of housekeeping genes versus cell specific/regulated genes? Be specific about everything’s role – what binds where and does what! A) 4pts -...

questions 1-4? 1. Use the following diagram of the lac I gene and lac operon.   Where would the lac repressor be bound in a (nonmutant) E. coli cell that is growing in no glucose and high lactose? (I = lac repressor gene; Z, Y, A = lac operon structural genes; P = lac promoter; O = lac operator) The repressor would not be bound P I P and O O 2. Euchromatin is associated with more loose and open organization of...
